Effect of isolated coronary artery ectasia on dispersion of P-wave and QT interval
The Egyptian Heart Journal, 2012 Background: Coronary artery ectasia (CAE) is well-recognized, angiographic finding of abnormal coronary artery dilatation, and detected in 0.3–5.3% of angiographic studies.

ARRITMIAS VENTRICULARES Y NUEVO SÍNDROME CORONARIO AGUDO EN PACIENTES CON INFARTO Y DISPERSIÓN DEL INTERVALO QT PROLONGADO / Ventricular arrhythmias and new acute coronary syndrome in patients with infarction and prolonged QT dispersion [PDF]
CorSalud, 2013 Resumen Introducción y objetivos: La isquemia miocárdica aumenta la dispersión del intervalo QT del electrocardiograma, ya que en estas circunstancias la duración del potencial de acción disminuye en la zona del insulto isquémico, al crear una dispersión

Effect of remifentanil on QT dispersion
Korean Journal of Anesthesiology, 2009 QT dispersion (QT(d)) is an indirect measure of the heterogeneity of ventricular repolarization and can be used as a risk factor for complex ventricular arrhythmias. We measured the effect of remifentanil on QT(d) and heart-rate corrected QT dispersion (QT(cd)).Sixty ASA class I and II patients, who were between 20 and 60 years old, and who were ...

QT Dispersion and Mortality in the Elderly
Annals of Noninvasive Electrocardiology, 2001 Background: The prognostic value of QT interval dispersion measured from a standard 12‐lead electrocardiogram (ECG) in the general population is not well established. The purpose of the present study was primarily to assess the value of QT interval dispersion obtained from 12‐lead ECG in the prediction of total, cardiac, stroke, and cancer mortality ...

Advanced Functional Materials, EarlyView.An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Advanced Functional Materials, EarlyView.Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...
